Ideas We Can Steal
from past legal systems
My previous post provided an example of the use of past legal systems in understanding our present legal system: the logic of feud law applied to high tech patent litigation. There are others, some of which suggest changes we might want to make to our system, ideas we could steal. For example …
The Athenian Rule
One problem with tort law is that a plaintiff who sues an innocent defendant in a system with legal error imposes a cost on him, in addition to his legal costs, the risk of losing the case and being found liable for damages. That may be a sufficient risk to persuade the defendant to pay off the plaintiff, settle out of court for less than the plaintiff claims — but possibly enough to make bogus suits a profitable form of extortion.
In Periclean Athens, their equivalent of a tort plaintiff who lost his case owed damages to the defendant, a sixth the amount he claimed the defendant owed him. That compensates the innocent defendant, makes suing someone unprofitable unless there is a substantial chance of winning the case, and gives plaintiffs an incentive to moderate their claims.
Plea Bargaining, Overcharging, and Athenian Law
Part of the problem with the modern system of plea bargaining is that a prosecutor can stack charges. Consider a defendant arguably guilty of an assault punished by a year in prison. The prosecutor charges him not only with that but attempted murder as well. Facing only an assault charge of which he believes himself innocent, the defendant might choose to go to trial with a reasonable hope of being acquitted. Charged with murder as well, facing a significant chance of a year in prison and a much smaller but non-zero chance of twenty years, he agrees to plead guilty to the lesser charge. Is there a way of changing the incentives of prosecutor and defendant to discourage that approach?
In Athens, a private prosecutor who failed to get 20% of the (very large) jury to vote for conviction could be fined. In modern legal systems the prosecutor is not a private citizen but an official acting for a government, which makes that approach less workable, but there might be other ways of doing it. One could, for instance, provide that if, in three different cases over a year, there was at least one charge on which fewer than four jurors voted for conviction, the prosecutor will be removed from office, a three strikes rule. That gives a prosecutor a reason not to file charges that he cannot support at trial.
If he files such charges anyway the rule provides no protection to the defendant, hence no reason for him not to give in to the threat; if he gives in the charges never get tried. Consider instead, or in addition, a rule providing that a defendant who is acquitted on any one charge must receive the lowest legal penalty on any charges he is convicted of. That reduces the power of the prosecutor’s threat, giving him an incentive to charge the defendant only with offenses the prosecutor thinks he can convict him of.
I doubt that either variant could get adopted in a U.S. jurisdiction at present but there are other places and will be other times.
A third way of doing it would be to limit prosecutors from prosecuting multiple charges for a single act. Arguably that rule is the natural extension of the legal rule against double jeopardy, so could be imposed by judges without any additional legislation. There would be line drawing problems defining what counts as a single act in some cases, but not all.

Marketable Torts
In modern tort law, it is up to the victim to identify and prosecute the tortfeasor. In the Icelandic system it was also up to him, once he got a verdict from the court, to enforce it. That could be a problem for a victim with insufficient resources, defined mostly in terms of the ability to use force, himself or with the aid of allies, to prosecute the case and enforce the verdict. The solution was to make claims marketable, permitting the victim to transfer his claim to someone better able to pursue it. He might or might not end up with a share of the damage payment — but then, crime victims usually collect nothing under our system. At least the offender would pay, giving potential offenders a reason not to violate the rights of even weak victims.
Consider the application of the same approach to modern tort law, where the victim needs resources to win his case even if not to enforce the verdict. A careless driver damages your car and perhaps you. You cannot afford a lawyer. You may be able to get a law firm to take the case on a contingency basis, in exchange for a share of whatever damages it collects. But you find it hard to judge which law firm will do the best job, collect the most. Even if you can afford a lawyer, you still do not know which one will do the best job for you.
If tort claims were fully marketable you could simply auction the claim off to the highest bidder.
That is not the only advantage of marketable tort claims. Consider a tort that does a small amount of damage to each of a large number of people. The current mechanism for dealing with such is a class action. An enterprising attorney persuades a few of the victims to appoint him to act for them, a judge to authorize him to pursue the case on behalf of all the other victims as well.
While the attorney has an incentive to try to win the case and collect damages, he also has an incentive to direct as much as possible of the payment to himself rather than to his supposed clients. Ideally the judge keeps him honest. If not, the attorney agrees with the defendant on a multi-million-dollar settlement consisting of a million dollars in real money to the attorney, ten million for the tort victims in the form of an offer of discounts on future purchases.
Suppose tort claims were marketable. A firm such as an insurance company that routinely deals with a large number of customers offers a discount to anyone willing to sign over to it all tort claims he might have in the next year for less than a hundred dollars. An enterprising lawyer concludes that ten million people have gotten mildly sick due to something wrong with a brand of canned beans, giving each a legitimate claim for ten dollars in damages.
The lawyer goes to the insurance company and offers to buy all of their claims for injury from canned beans. He makes the same offer to other firms that have similarly purchased their customers’ small claims. When he is done, he owns three million claims for ten dollars each. He goes to the bean company and offers to settle for eighty cents on the dollar, twenty-four million dollars. If they turn him down he sues, not on behalf of the victims, who have sold their claims to him via middlemen, but for himself. There is no need for an attorney to pretend to represent millions of people who have never heard of him, no need for a judge to monitor the settlement to make sure it is fair to the victims. The victims have been paid in advance.
Iceland had marketable claims in the tenth century. America does not have them yet. Our legal system is more than a thousand years behind the cutting edge of legal technology.1
To Catch Up With Eighteenth-Century England
From time to time someone commits a crime that his government approves of. Examples in my lifetime include murder (of Black Panthers Fred Hampton and Mark Clark by Chicago police in 1969) and perjury (by Director of National Intelligence James Clapper testifying to Congress in 2013). Criminal prosecution in our legal system is by the government, so crimes the government approves of are unlikely to be prosecuted and neither of those was. But the Black Panther shooting produced a civil case that eventually settled for 1.85 million dollars, paid by Chicago, Cook County and the federal government.
A civil suit is one way of dealing with a crime that the government chooses not to prosecute, but not all crimes produce grounds for such a suit. In eighteenth-century England, the solution was much simpler: Any Englishman could prosecute any crime.2
Someone convicted in an ordinary criminal prosecution could be pardoned by the king — in our legal system by the president — but there was a form of private prosecution, an appeal of felony, which treated the criminal prosecution as a private case, like a tort case.
“If the appellee be found guilty, he shall suffer the same judgement as if he had been convicted by indictment: but with this remarkable difference; that on indictment, which is at the suit of the King, the King may pardon and remit the execution; on an appeal, which is the suit of a private subject, to make an atonement for a private wrong, the King can no more pardon it, than he can remit the damages recovered in an action of battery.” (Blackstone 1884, Bk 4 Ch 23)
Suppose we wanted to change our system to deal with the problem of the government refusing to prosecute crimes it approves of. We could do so by changing our law to permit a private citizen to institute a criminal prosecution against a defendant whom the state failed to prosecute. That sounds like a radical proposal but a version of it already exists in modern American law. Some statutes provide the option of a private attorney general, prosecution by a private citizen. As in English law in the late eighteenth century, the successful prosecutor could, at the option of the judge, be awarded attorney fees to cover his costs. I am proposing a modest expansion of the existing rule — to cover all crimes.
One question remains: Is the result a good one? Seen from one side, it is a precaution against governments murdering people they don’t like. Seen from the other, it reduces the ability of the legal system to ignore illegal acts that are not worth punishing.
In the U.S. at present, it is illegal for college students who are under twenty-one to buy, possess, or consume alcoholic drinks or for others to provide alcoholic drinks to them.3 Would it be a good thing for a student with a grudge against his ex-girlfriend or her new boyfriend to be able to have one or both arrested, charged with (depending on the state and circumstances) a misdemeanor or felony and, if convicted, jailed for several months, conceivably several years?
Here again, evidence from past legal systems is relevant. Under the English game laws, some wild animals were considered property of the Crown and hunting them restricted to the king or those he had authorized. The result was that the right to hunt such animals did not always belong to the owner of the land on which they were hunted. The restriction was widely ignored, providing opportunities for the threat to prosecute to be used to extort money from landowners guilty of the crime of hunting the king’s deer on their own land.4
A possible compromise might be to permit private prosecution only against government employees. Think of it as an updated version of Mencken’s proposal.
“… any [American citizen], having looked into the acts of a jobholder and found him delinquent, may punish him instantly and on the spot, and in any manner that seems appropriate and convenient―and that, in case this punishment involves physical damage to the jobholder, the ensuing inquiry by a grand jury or coroner shall confine itself strictly to the question of whether the jobholder deserved what he got.”

In Florida, possession is a misdemeanor punishable by up to sixty days imprisonment plus suspension of driving privileges. In Illinois, providing alcohol to someone under age is a misdemeanor with a penalty up to a $2,500 fine and a year in jail or a felony with a penalty of a year or more in jail and a fine of up to $25,000.

I recommend *Legal Systems Very Different From Ours* too. My only real complaint is it isn't long enough. My only trivial complaint is not knowing what the rationale was behind the Athenian rule that you could search someone's house only if you did it naked. Was it so the humiliation would prove you were serious, or was it to prevent you from planting evidence?
Pericles's loser pays doesn't go far enough. I would make losers pay all restitution -- not just attorney fees and court costs, but time off work, travel expenses, witnesses, every single thing the winner had to spend. It would go a long way towards discouraging frivolous complaints.
I would also redefine outlawry. If you don't pay your verdict debt, you are an outlaw and cannot file any complaint for less than your unpaid verdict debt. This allows the winner, neighbors, and the general public to steal from the outlaw, as long as they keep their thieving and ancillary damages to less than what the outlaw owes. It not only lets the public know who the outlaws are, it also encourages criminals to show remorse and convince their victims to convert the verdict debt into a loan repaid in installments.
This outlawry also slows down frivolous litigation. Whatever the vexatious litigator owes in verdict debt sets a bar for succeeding complaints, and each loss ramps it up, until the vexatious litigator runs out of room to litigate.
To reduce overcharging, I would prohibit dropping any charges once filed; take all to trial, or drop them, or negotiate the deal. Subtract the maximum charge for all acquitted charges from the actual sentencing; if it comes out negative, pay the defendant the difference from the prosecutor's budget. I believe most states have some standard formula for paying for wrongful convictions; use that.
One problem with selling torts is that the victim goes from being a victim with skin in the game to a witness who no longer has as much incentive to tell the truth. I don't mean outright perjury or selling out to the other side, but just lacking the same incentive as the victim wanting restitution.
Suppose it costs $1000 to prosecute each of those canned beans cases; the victims will still only get $10, but the beans company pays $1010 plus its own costs. Loser pays full restitution encourages the beans company to settle with as little fuss as possible without needing class action lawsuits or the victims to sell their cases.
This is a history of private prosecution in America and how the government came to monopolize criminal prosecution. It was entirely news to me. Apparently private prosecution was the norm until, more or less, after the Civil War.

I'd like to bring back tar and feathering and other vigilante pre-emptive justice, with the proviso that if the damage incurred by tar and feathering exceeds that which the victim previously inflicted on the vigilante, then the vigilante can be prosecuted for assault in the usual manner. If some bureaucrat holds up a project and costs the developer a million bucks, tar and feathers, or even a day in the stocks or pillory with locals throwing tomatoes and eggs, seems entirely appropriate.
...A possible compromise might be to permit private prosecution only against government employees...
